987abc8e3d When trying to find the boot partition, look at all partitions marked as ffs 
or swap partitions.  Booting from a miniroot on the swap partition will
detect the miniroot as the boot partition (if the bootblock loader passes
the boot partition offset to the kernel).

62e846995f findroot() fix for kernels configured "root on ? type ?" (i.e., disk) 
that are booted via MOP or tftp:: if we don't find a block device name
that matches bootdev, give up and let setroot() force RB_ASKNAME.

b14e608272 Amiga custom chip audio hardware driver, by Stefan Thesing 
(thesing@cs.uni-sb.de), heavily hacked upon by me to
- make it work with -current audio system
- make it shut off Amiga audio DMA only at appropriate places.
XXX A couple of bugs still remain, which well be handled later.
XXX Among them: only mono output; doesn't refuse to handle input, but chokes;
will not play last millichunk (is this 20 ms?) of data.

28fd103fd9 Temporarily disable wds driver. The driver statically allocates a huge 
bounce buffer, which breaks installs on 4Meg machines using the new
ramdisk install system. We'll bus_dma the driver and then it should be
fine to put back in to the normal INSTALL kernel.

91f7efbaf9 Fix crash dump device selection after the recent swap changes: 
- If RB_ASKNAME, prompt for the dump device, defaulting to
  partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
  a disk, select partition b.  (which was the previous default dump
  partition)

Note, dumps to a local disk now work even if root is on nfs.

a0d9d3bc54 Allow to boot from DOS if a XMS manager is installed. 
XMS is recognized and used as temporary buffer for the kernel image.
The processor must still be in real mode at program start, so EMM386
or QEMM are not allowed. W*95 is OK.
Written by Martin Husemann (pr port-i386/3336).
Completely separated from other bootloaders for sanity.
